论文摘要
高能量的质子/电子束固定目标实验扩大了探测子GEV暗物质和相关相互作用的机会。在这项工作中，我们探讨了沙丘对亚gev瘦恐惧症暗物质的敏感性，即这种暗物质几乎与瘦素伴侣。 Baryon数量学理论可以预测植物性冷暗物质粒子候选物的存在。在我们的工作中，暗物质候选者被认为是标量，其质量是由新的Baryonic仪表组$ u（1）_ {b} $的对称破坏定义的。在这种情况下，轻标度暗物质与标准模型通过矢量玻色子介质$ v_ {b} $伴侣，属于baryonic仪表组$ u（1）_ {b} $。这种瘦小的暗物质主要伴随着夸克。在这种情况下，Dune探索了$α_{B} $的新参数空间，以探索瘦小暗物质的候选。这个新的参数空间允许$α_{b} $获得低于$α_{b} $的当前退出约束值，即$ 10^{ - 6} $。
Highly energetic proton/electron beam fixed target experiments extends an opportunity to probe the sub-GeV dark matter and associated interactions. In this work we have explored the sensitivity of DUNE for sub-GeV leptophobic dark matter i.e. this dark matter barely couples with the leptons. Baryon number gauge theory can predicts the existence of a leptophobic cold dark matter particle candidates. In our work, the dark matter candidate is considered to be scalar whose mass is defined by the symmetry breaking of new baryonic gauge group $U(1)_{B}$. In this scenario a light scalar dark matter couples with the standard model candidates via vector boson mediator $V_{B}$ which belongs to the baryonic gauge group $U(1)_{B}$. This leptophobic dark matter dominantly couples to the quarks. Under this scenario new parameter space for $α_{B}$ is explored by DUNE for leptophobic dark matter candidates. This new parameter space allowed $α_{B}$ to get lower value than the present exiting constraint value of $α_{B}$ i.e. $10^{-6}$.
